    The title compound, C18H20N2OS, displays whole-molecule disorder over two adjacent sets of sites with an occupancy ratio of 0.630 (11):0.370 (11). In each disorder component, the cyclohexyl ring shows a chair conformation with the exocyclic C-C bond in an equatorial orientation. The dihedral angles between the cyclohexyl ring (all atoms) and the naphthyl ring system are 36.9 (6) for the major component and 20.7 (12)° for the minor component. Each component features an intramolecular N-H⋯O hydrogen bond, which closes an S(5) ring. In the crystal, inversion dimers linked by pairs of N-H⋯S hydrogen bonds generate R22(8) loops for both components. Aromatic π-π stacking interactions [shortest centroid-centroid separation = 3.593 (9) Å] and a C-H⋯π interaction are also observed.
